Product description Brand name and product description

Klorfasil is a locally produced chlorination product for drinking water treatment in rural Haiti. This NGO (also named Klorfasil) sells granulated chlorine, sodium dichloroisocyanurate dihydrate (NaDCC), for disinfection. Klorfasil is intended for household use to reduce transmission of water-borne disease and incidences of diarrhoea.

Target region(s) Target region for distribution/implementation (listed by country if specified)

1 ounce bottles, contain 70 mg of granulated chlorine, weigh 45 grams each is enough for treating 20L water. Each bottle is labeled in Haitian Creole, with product composition, volume of water treatable, and instructions. The chemical NaDCC uses hypochlorous acid to disinfect. The compound has been proven for reducing microbial contamination.

Compliance with regulations Product certifications and standards referenced by designer/manufacturer

NSF / ANSI Standard 60: Drinking Water Treatment Chemicals: Klorfasil is not specificially listed as complying, but dozens other companies selling sodium hypochlorite products for drinking water treatment are approved. This certifies that chemicals are safe at the maximum dose and that any impurities are below the maximum allowable limit.

US Environmental Protection Agency (EPA) Registration: Klorfasil is not registered with the US EPA. Other products that use NaDCC for drinking water treatment are registered, however. For example, the manufacturer Occidental Chemical has had a NaDCC granule product registered for drinking water disinfection since 1996.

World Health Organization (WHO): The World Health Organization does not currently approve products for use to treat drinking water. However, the Guidelines for Drinking Water Quality lists NaDCC tablets as a point-of-use water treatment method commonly used to prevent diarrhea in developing countries and for travellers. Granular NaDCC is not specifically listed, although tabular NaDCC should perform the same as granular NaDCC if applied at the proper dose.

The manufacturer tests the disinfected water in safe water storage container using DPD 1 Rapid test tabs, from LaMotte. They fill plastic test tube with 10 mL sample from the water, add DPD tablet, cap tube and shake gently. DPD tab will turn red in the presence of free chlorine; Klorfasil looks for a 0.5 ppm free chlorine residual after 30 minutes. If no free chlorine residual after 30 minutes, the water source must be changed to something with lower chlorine demand, or a second dose should be used. Interviewwithrepresentative
